A New Imide-pyrazine Zinc(II) Binuclear Complex; in SituSynthesis and Crystal Structure Determination

New zinc(ii) binuclear complex, [zn2(μ-dpzca)(2-mpzci)cl3] (1)(where dpzca is n-(2-pyrazylcarbonyl)-2-pyrazinecarboxamidate anion and 2-mpzci is methyl pyrazine-2-carboximidate), was synthesized from the reactionof zncl2.7h2o and 2-cyanopyrazine in methanolic solution at 65 °c. thiscomplex was thoroughly characterized by elemental analysis (chn-o), ir, uvvis,^1h nmr spectroscopy and its structure have been determined by the singlecrystalx-ray diffraction. the spectroscopic investigations and x-ray structuralanalysis indicated that by methanolysis and in the presence of zncl2.7h2o saltthe 2-cyanopyrazine ligand converts to methyl pyrazine-2-carboximidate.furthermore, the bis(2-pyrazinecarbonyl)amidate anionic ligand have beenprepared from 2-cyanopyrazine in the presence of zncl2.7h2o salt in methanolicsolution.
